We all know that technology and circuits are everywhere. It’s in our cars, our homes, and even on our bodies! RFID technologies are becoming more popular for many different reasons. If you’re considering buying RFID wallets, it might be helpful to understand how these

According to the estimation by Bureau of Labor statistics, five to ten arc blast incidents occur every other day in the United States of America. Arc flash sprays molten metal droplets at very high speed to the people standing near the accident site. These drops are strong enough

Do you have an electronic device that requires accurate timekeeping? Or does your project require you to count seconds, minutes, hours, and even months?  Well, if you don’t know how to go about it, don’t worry, you’re in the right place. Projects that involve timekeeping,

When most people start working with Arduino microcontrollers, they aren’t aware of all the expansion modules and shields available to them. While the Arduino Uno is one of the most popular microcontrollers globally, it doesn’t feature Bluetooth connectivity.  Certai

An ideal power supply unit must feature a variable voltage and current power supply circuit. The property is most important in common laboratory uses and in various applications that require AC voltage regulation.  A voltage regulator with manipulatable current limits faci

It’s not great when water spoils that circuit you’ve been working on for some time. And, it’s even more frustrating when it hurts a device that needs protection from water or rain. Luckily, we have a solution. The water sensor circuit is all you need. A water sensor circuit is als

Generally, an IC 4060/CD4060 timer chip is a Timer IC or oscillator in some instances. It belongs to an IC 4000 series of Integrated Circuits and operates in a power supply ranging from 3V to 15V. Other than using it to get a high-graded time precision during oscillation of d

Inductors are rare for hobby electronics. However, they’re essential to learn about if you’re doing anything that involves alternating current (AC). They’re as popular as resistors in applications that use AC. They impose changes in the flow of current. As a resu

Many fundamental concepts in the technical world are hard to deal with because of how deceptive their meanings can be. Unfortunately, Hysteresis is one of those basic concepts.  You may have tried searching out the concept only to give up or meet something so complicated a

Various electronic circuits come with visual indicators and sometimes even appliances. Also, these visual indicators are important because they help show many things happening with the course or appliance at that moment. Like when your flashlight is fully charged or when your tele

Building an AM broadcast radio receiver can be a fun project. But, certain limitations can hinder your radio experience—like weak AM signals. AM reception can be tricky because of its high susceptibility to electrical noise and other different sources of interference. While most r

Capacitors are important devices necessary for most electronic applications. Plus, they can store electrical energy making them powerful devices. However, it doesn’t come without faults. Capacitors can suffer from leakage current which is the result of imperfections in the oxide l

About Voice Changer Circuit, Voice modulation is a captivating and fun project that we’ve had to work on so far. Often, its circuitry involves transformation or a change of a human voice into a new one.  Learning from the movie Doctor Who, it has been delightful t

An Arduino proximity sensor is a handy, inexpensive gadget that detects the presence of an object within its sensing range. This could be anything from a human to a pet or even something as small as a bug! It’s really easy to make one yourself.  Have you ever wanted

A 12-volt battery is a rechargeable battery that has grown in popularity because of its many different uses. As an electronics enthusiast, your need to get knowledge and try out other projects constantly grows. Today, you get to learn about 12-volt Batteries! In this article, w

All electrical outlets get faulty from time to time. When an electrical device develops a fault, such defects often arise due to a disruption in one of the device’s wires. Without the continuity tester circuit to help you troubleshoot the device’s circuit and find wher

Technology goes hand in hand with robotics and electronics. At the center of all these is the electronic circuit board, and the most common circuit board in the electronics world is the Arduino circuit board. People also think Aduinos are microcontrollers, and however, they are ci

Sometimes it becomes tiring to have to get out of your comfort zone and walk to your television just to switch channels or to adjust the volume because you misplaced your TV’s remote control or failed to buy new battery cells. Well, having a phone equipped with an IR blaster

Most modern devices use piezoelectricity as a component of their Printed circuit boards (PCBs). For example, your quartz watch needs piezoelectricity to regulate time. Besides, microphones and even your beloved Siri also need it for voice recognition. But how does piezoelectric wo
